HOUSTON, Dec. 4, 2012 — A single laser blast can activate plasmonic nanobubbles that selectively kill diseased cells while at the same time treating others, and leaving neighboring healthy cells untouched.
Fiber Optic ‘Wrench’ Twists, Turns Tiny Particles
ARLINGTON, Texas, Dec. 3, 2012 — The fiber optic equivalent of the world’s smallest wrench, dubbed the fiber optic spanner, can precisely twist and turn microscale objects in any direction and along any axis without moving any optical component. Developed at The University of...
NIR Imaging Gets Big Boost
STANFORD, Calif., Dec. 3, 2012 — Studying arterial diseases and therapies just got easier, thanks to a new fluorescence imaging technique that allows researchers to visualize the blood flow of living animals with unprecedented clarity. The Stanford University technique, called...
OCT images blood vessels that feed cancer
VIENNA and MUNICH – An optical coherence tomography (OCT) technique that noninvasively maps the network of tiny blood vessels in the epidermis could soon help doctors better diagnose, monitor and treat skin cancer. Scientists at Medical University Vienna (MUW) are the...
Prism Awards Finalists Offer Solutions to Big Problems
Dec 1, 2012 — Finalists from Europe include tools for pollution monitoring, manufacturing, brain imaging and more. Sensors for monitoring environmental toxins and detecting explosives, powerful new lasers for biophotonics, and tools for lithography and...
Spectroscopic “fingerprints” diagnose brain tumors
LANCASTER, UK – A breakthrough in brain tumor diagnosis uses infrared and Raman spectroscopy to differentiate healthy from diseased tissue based on individual biochemical-cell “fingerprints.” Currently, it is difficult for surgeons to determine where...
18 Firms to Vie for $94M at Invest in Photonics
BORDEAUX, France, Nov. 30, 2012 — Eighteen emerging technology companies from around Europe have been selected to participate in a special funding session at the two-day international business partnering convention Invest in Photonics next month in Bordeaux, a growing industrial...
Implantable Silk Micromirrors Enhance Imaging
MEDFORD/SOMERVILLE, Mass., Nov. 30, 2012 — Silk-based implantable optics that significantly enhance tissue imaging can simultaneously enable photothermal therapy, monitor drug delivery and administer drugs.
X-ray Laser Helps Fight Sleeping Sickness
MENLO PARK, Calif., Nov. 29, 2012 — A weak spot in the parasite that causes African sleeping sickness, a disease that kills an estimated 30,000 people each year, has been mapped using an x-ray laser, pinpointing a promising new target for treating the fly-borne illness.
Oclaro Selling Film Business to II-VI
SAN JOSE, Calif., Nov. 26, 2012 — Optoelectronic components maker Oclaro Inc. plans to sell its Santa Rosa-based thin-film filter business to II-VI Inc. subsidiary Photop Technologies, the company announced today. Under the $27 million cash deal, Oclaro also will sell its...
Tiny Probes Dramatically Boost Raman Signals
ST. LOUIS, Nov. 26, 2012 — Novel gold nanoparticles can goose the signal from Raman reporters, or molecules whose jiggling atoms respond to a probe laser by scattering light at characteristic wavelengths. The discovery could lead to better-targeted drug delivery and deeper...
